Highlights ■ Hyperprolactinemia can be present in non-functioning pituitary adenomas because of the stalk effect. ■ Absolute prolactin levels may not always be reliable in discriminating non-functioning pituitary adenomas from prolactinomas. ■ Prolactin normalization after 48 h of 0.25mg cabergoline intake could be a strong predictor of non-functioning pituitary adenomas (100% sensitivity and specificity). ABSTRACT Objective: Clinical, imaging, and laboratory differentiation between non-functioning pituitary adenomas (NFPAs) and prolactinomas can be challenging in clinical practice because of their similar presentation and […]

ABSTRACT In this article, we present a case of diffuse follicular variant papillary thyroid carcinoma with pituitary metastasis, which is a rare cause of pituitary metastasis. The follicular variant of papillary thyroid carcinoma is an uncommon variant of papillary carcinoma. A 74-year-old male was presented with weakness, fatigue, and a decreased appetite. The patient was diagnosed with secondary adrenal and thyroid insufficiencies. Imaging revealed a pituitary mass with suprasellar extension, right cavernous sinus invasion, and optic chiasm compression. Thyroid ultrasonography […]
